Title: Surface acoustic wave element
Inventor: TOTANI KAZUYUKI
IPC: H03H9/145
Filed: 1996-07-10
Abstract: PROBLEM TO BE SOLVED: To provide a surface acoustic wave element which has an excellent filter characteristic while its size is reduced. SOLUTION: The spurious radiation by reflection from an input-side lead-out electrode 3x and output-side lead-out electrode 5x is reduced by making the electrodes 3x and 5x of a metal having a vibration absorbing property. In addition, the spurious radiation caused by the reflection from the edge of a chip can be reduced by means of a vibration absorbing wall 11 provided near the outer periphery of the chip. Therefore, the deterioration of the filter characteristic of a surface acoustic wave element can be prevented even when the crossing length of an interdigital electrode (IDT) is reduced. Moreover, it becomes unnecessary to apply a resin having high elasticity to the outer periphery of the chip.

Title: Connecting structure for circuit board
Inventor: MIYAKE TOSHIHIRO
IPC: H05K3/36
Filed: 1994-07-07
Abstract: PURPOSE:To provide a connecting structure for circuit board with high reliability of which wiring interval is made smaller and connecting strength is large. CONSTITUTION:A circuit board 2 is provided with a part 5 with large wide where an end part of a first connecting land 3 is made large in width, so that a solder forms a fillet in the part 5, resulting in increasing connecting strength against a strain caused by the flexibility of a flexible board 1.

In addition, the part 5 is arranged in a zigzag pattern, making an interval between wirings to be smaller. Further, since the formed fillet can be observed visually from the side of the transparent flexible board 1, the inspection after soldering can be performed easily, so that defective products may be hardly shipped.

Title: Method of changing threshold value of mos transistor
Inventor: WATANABE MITSUHISA
IPC: H01L29/78
Filed: 1986-07-31
Abstract: PURPOSE:To stabilize the characteristics of an MOS transistor and reduce the process time by a method wherein ions are implanted from the above of a gate electrode into a channel region after an oxide film on the gate electrode is removed by etching. CONSTITUTION:When impurity ions are implanted into channel regions in order to change the treshold values of some of MOS transistors after the MOS transistors are formed, the impurity ions are implanted after oxide films on the gate electrodes are removed.
